DRAW'-BAR FOR HARROWS.

Specification of Letters Patent.

Application filed August :26, 1909. Serial No. 514,772.

10 all 107mm it may concern:

Be it known that I, F RANOIS F. Anix, a citizen of the United States,residing at Boone, in the county of Boone and State of Iowa, haveinvented a certain new and useful Draw-Bar for Harrows, of which thefollowing is a specification.

The object of my invention is to provide a draw bar for harrows or otherimplements, of simple, durable, and inexpensive construction, sodesigned as to be easily drawn through the common form of wagon gate.

A further object is to provide a folding draw bar for harrows or otherimplements, arranged with clamps designed to fix rigidly the pivotedsections.

A further object is to provide a draw bar for harrows or otherimplements, with draw rods arranged to pull evenly on all the see tionsof the bar when in an extended position, and on the central draw barsection only when in a folded position.

My invention consists in the construction, arrangei'nent, andcombination of the various parts of the device, whereby the objectscontemplated are attained, as hereinafter more fully set forth, pointedout in my claims, and illustrated in the accompanying drawings, inwhich- Figure 1 shows a plan View of the draw bar extended. Fig. 2 showsa side elevation of same. Fig. 3 shows a plan View of the draw barfolded. Fig. 4. shows a side view of same. Fig. 5 shows a detailsectional view taken on the line 5-5 of Fig. 2.

Referring to the accompanying drawings, the central section of the drawbar is indicated by the reference numeral 10. The two end sections 11are pivotally connected to said section by hinges comprising theinwardly extended pieces 12 fixed to the sections 11, the outwardlyextended pieces 13 fixed to the section 10, and the bolt 14 pivotallyconnecting said pieces 12 and 13. The ends 15 and 16 of the sections 10and 11 are beveled as shown in Fig. 1 and in dotted lines in Fig. 1.

The clamps 17 are pivotally connected to the central section 10 at oneend, and are arranged with notches 18 at the other end to engage thebolts 19. The hand screws 20 firmly secure the clamps 17 relative to theend sections 11, such arrangement rigidly securing the end sections 11to the central section 10.

The eye bolts 22 and 21 are fixed to the central and end draw barsections and receive the draw rods 21 and 23, each of which comprisestwo sections connected by rings 25, said draw rods 23- and 24 engagingthe ring 26.

In the operation of the draw bar, when used in connection with a threesection harrow, the clamps 17 are swung into engagement with the bolts1%), and the hand screws 20 are tightened down to keep the end sections11 of the draw bar in an extended position relative to the centralsection 10. The harrow sections are then fixed to their respective drawbar sections. The clamps 17 prevent the end sections of the i draw bar11 or the end sections of the harrow from tilting upwardly as power isapplied to the draw rods 22-3 and 2 1. If it is desired to pass througha gate, the hand screws 20 are loosened and the clamps 17 a re swungfrom engagement with the bolts 19. th the end sections of the draw barand the harrow are then folded into positions as shown in Figs. 3 and 1.The draw bar and harrow in this form may then easily pass through a gateor door. The draw rods 2-1. on the central section 10 receive at thistime all the power applied, the draw rods 23 being freely suspended inposition as shown in Figs. 3 and 4.

I claim as my invention:

1. A draw bar, comprising a central sec tion, end sections pivoted tosaid central section, plates pivoted at one end to one section andoverlapping another section, and means for clamping the free ends of theplates to said section for securing the sections in alinemcnt.

2. A draw bar, comprising a central section, end sections pivoted tosaid central draw bar section, draw rods broken and connected by rings,extending from a main d'aw ring to the central and end draw barsections, and notched clamps pivoted to the central draw bar section,bolls in the end draw bar sections to receive said notches in saidclamps, and hand screws for securing the free ends of said clamps to theend draw bar sections.
